at 187°, and with water yields ethyl alcohol, acetone, and carbon
dioxide.
If the solid product obtained by the aotioa of sodium upon acetic
ether is acted upon by ethyl iodide, different compounds are formed,
which can be separated by fractional distillation; amongst them there
are ethers of the fatty acids, such as ethyl-acetic acid or butyric acid,
which is produced by the substitution of ethyl for one atom of
hydrogen in the methyl group of acetic aoid, the radical methyl being
thus changed into propyl:—

In a similar way diethyl-aoetie acid, an isomeride of caproic acid,
is obtained;—

Another class of compounds are formed by the action of ethyl
iodide upon the sodacetone-carbonic ethers:—

The ethyl ethacetone-carlonate thus fovmed is readily decomposed
by baryta-water, the products being alcohol, barium, carbonate, and
